People compare them constantly. Almost nothing about them is the same: the material, the use, the price, and the idea each has of what a bag is.
What they share: a silhouette
The comparison is not unreasonable. The jelly firkin borrows the grammar of the classic leather city bag — a trapezoid volume that stands up on its own, a notched flap, a lock-style closure, two rounded top handles with visible stitching. That architecture is what the eye recognises, and it is why the name stuck.
The resemblance ends there.
The material: leather against TPU
A traditional luxury bag is made of leather. It takes a patina, it needs feeding, it can be repaired, and it fears water.
The Jelly Firkin is made of translucent TPU — thermoplastic polyurethane, the material used for technical equipment. It does not develop a patina; it catches light. Rain, sand and splashes are non-events. And it lets people half-see what you are carrying, which no leather will ever do.
This is not a cheaper substitute. It is a different proposition.
Price: two different worlds
A leather bag from a major house is counted in thousands of euros, with waiting lists and a resale market attached to it. The jelly firkin is counted in tens of euros: €64.90 for our signature model.
That gap is not only a budget question. It changes your relationship with the object. A €64.90 bag goes to the beach, to a festival, out in the rain. You do not protect it. You use it.
How each one is used: discretion against display
The classic luxury bag is built on timelessness and discretion. The jelly firkin does the opposite: its translucent material turns whatever is inside into part of the look. A book, sunscreen, sunglasses, a bright charm — all of it becomes visible and deliberate.
That is a large part of why it works for a generation used to showing its day as it happens. The bag no longer hides. It tells.
Is it a counterfeit?
No, and the distinction matters.
A counterfeit copies a brand: its name, its logo, its distinctive signs, in order to pass itself off as authentic. The jelly firkin carries no logo, no signature and no brand element belonging to a third party. What it takes up is a silhouette, which belongs to the common vocabulary of leather goods — in the same way the double-breasted jacket and the pleated trouser belong to the common vocabulary of clothing.
If a seller offers you a bag carrying the name or logo of a luxury house, it is not a jelly firkin: it is a counterfeit, and buying one exposes you to penalties in several countries.
Which one should you choose?
The question barely arises, because the two are not competitors.
A leather bag is a long-term investment to be looked after. A jelly firkin is a seasonal accessory: coloured, water-resistant, matched to what you are wearing rather than to your status. Many of our customers own both and do not take them out in the same circumstances.
What if you want both?
Since autumn 2026 there is a third answer: the Maison now makes the opaque bag too. Le Firkin takes exactly the silhouette described above — flap, padlock-style clasp, round topstitched handles — in full-grain cowhide leather, lined in leather, from €104.00 to €149.00 depending on size. The same line exists in PU (faux leather), a synthetic material containing no leather, from €80.90: it has its own page, Le Firkin PU. The four PU shades — Camel, Ivoire, Onyx, Éléphant — also exist in leather, which offers nine, and the buckle can be chosen in gold or silver on both.
Full grain means the top layer of the hide, the one that carries the natural grain: neither sanded down nor covered with a film. It is the most hard-wearing part of the leather, and the only one that truly takes a patina — the difference between a bag that ages and a bag that wears out.
Everything in this comparison still holds for it: that leather fears water, it is fed twice a year, and it shows nothing of what it carries. It simply does not have to cost thousands of euros to be real leather.
Le Firkin PU, for its part, does not take on a patina: it keeps its original look, is unaffected by water and wipes clean with a damp cloth. It contains no leather — it is a synthetic material, and the price difference between the two bags corresponds exactly to that difference in material.
And for anyone who wants the depth of a grain, the Héritage offers premium-quality PU (not leather) with an embossed reptile grain in nine autumn shades, at €104.00.
